Maho is a narrow beach with calm shallow water. Sea grass out a bit, so if you're snorkeling, you'll probably see turtles. Across the road is are a few pop up shops, carry out snack bar, equipment rentals, and bathrooms. (pic is across from Maho) It is pretty sunny on the beach, also get very crowded. We were staying on island so I don't know if there is chair rentals as we brought our own. If you have never been to St John, I suggest going to Trunk Bay...more beach, snack bar, bar, few shops.
